The Role Of Critical Thinking Skills In Practicing Psychologists’ Theoretical
Orientation and Choice of Intervention Techniques
Ian Randolph Sharp
James D. Herbert, Ph.D.
Over the past two decades, professional psychology has witnessed a growing
movement towards the utilization of psychotherapies that have empirical support.
Despite this development, therapies that have not been empirically supported
continue to experience widespread use. Concurrently, a collection of novel
interventions, known as Power/Energy therapies (P/ET’s), has emerged. Although
these therapies are based on questionable theoretical foundations and enjoy little or no
empirical support, their popularity with clinicians appears to be strong and growing.
There is scant research examining individual differences with respect to the practice
habits of professional psychologists. The present study examined whether critical
thinking skills are a factor in psychologists’ choice of therapeutic interventions,
including their use of P/ET’s. As hypothesized, participants who reported using a
number of techniques from Power and Energy therapies scored significantly lower on
a measure of critical thinking skills. Also as hypothesized, individuals who reported
using a number of cognitive-behavioral techniques scored significantly higher on the
measure of critical thinking skills. Implications and suggestions for future research
are discussed.
Up until the1950’s, what little empirical research there was on psychotherapy
largely focused on process. Pioneers like Carl Rogers examined what happened in
therapy sessions and how the behavior of clients and therapists affected the selfunderstanding and insight of the clients. For example, Rogers argued that being
genuine with the client and showing unconditional positive regard were essential
ingredients of the therapeutic process and led to client improvement (Rogers, 1957).
Few questioned the overall effectiveness of psychotherapy.
In 1952, Hans Eysenck altered this focus on process by calling into question
the effectiveness of psychotherapy. Eysenck published a seminal review article that
concluded that “neurotics” who received psychotherapy essentially mirrored those
who did not in terms of improvement (Eysenck, 1952, 1992). He concluded that
psychotherapy had failed to demonstrate effectiveness. He further concluded that the
lack of scientific evidence for the effectiveness of psychotherapy called into question
its use until such evidence was demonstrated. Eysenck’s conclusions galvanized
psychotherapy research and its change in focus from process to outcome; studying the
components of therapy was potentially obviated by the potential that therapy simply
did not work (Hill & Corbett, 1993).
Since Eysenck's early warnings of the potential lack of effectiveness of
psychotherapy, a tremendous body of research has accumulated showing that
psychotherapy does generally work (see Hunsley & DiGiulio, 2002 for a recent
review). In 1967, Gordon Paul reviewed the psychotherapy literature and concluded
that the greatest need was for outcome research. His frequently quoted question set
the stage for treatment outcome research: "What treatment, by whom, is most
effective for this individual with that specific problem, and under which set of
circumstances?" (Paul, 1967, p. 111). With the publication of the third edition of the
Diagnostic and Statistical Manual of Mental Disorders (DSM-III; American
Psychiatric Association, 1980) treatment outcome research was now able to focus on
interventions for relatively clearly defined disorders. Prior treatment research had
focused on nebulous conditions and patient populations (e.g., “neurotics”) but could
be now informed by operationally defined syndromes. Similarly, the delineation of
treatments themselves would provide the same control for research. Thus, treatment
manuals provided a more valid and reliable way of testing the efficacy of a particular
treatment. Beck et al.’s Cognitive Therapy for Depression was one of the first in a
line of treatment manuals that had demonstrated efficacy (Beck et al., 1979).
Empirically supported treatment (EST) manuals have since been developed for a wide
range of problems, from Irritable Bowel Syndrome to Schizophrenia. Despite the
strong response to Paul’s appeal to focus on outcome research and the subsequent
robust findings of the effectiveness of psychotherapy, a persistent movement has
pervaded psychotherapy research. The proponents of this movement have argued that
although psychotherapy in general is effective, there is no specificity in terms of
specific interventions for specific problems. In other words, the various orientations
and approaches to psychotherapy are simply variations on a theme and the
distinctions between them are meaningless with respect to treatment outcome.
1.1 Is the Dodo Bird Effect Extinct?
In 1936, Rosenzweig quoted the Dodo bird from Alice in Wonderland to
make a point that psychotherapies are effective because of shared factors, “Everyone
has won, and all must have prizes” (Carroll, 1865/1962). This notion that all
psychotherapies are equally effective has come to be known as the Dodo bird effect.
Luborsky, Singer, & Luborsky (1975) published an influential paper that reviewed
the extant psychotherapy outcome literature at that time and concluded that all
psychotherapies had roughly equivalent efficacies, thereby lending support to the
Dodo bird effect (Luborsky, Singer, & Luborsky, 1975). Another influential study by
Smith, Glass, and Miller also found psychotherapy was effective in general and that
no one treatment was superior to another (Smith, Glass, and Miller, 1980).
The most frequently used analytical tool in defense of the Dodo bird effect has
been the meta-analysis (e.g., Smith, Glass, and Miller, 1980). Utilizing metaanalysis, a number of more recent studies appear to confirm the Dodo bird
hypothesis. For example, Wampold et al. (1997) conclude from their meta-analysis
of psychotherapy outcome studies that treatment effects are roughly equivalent across
approaches, though they caution that it is cannot be said that all therapies are
equivalent across specific disorders. They conclude their paper with, “Why is it that
researchers persist in attempts to find treatment differences, when they know that
these effects are small in comparison to other effects, such as therapists effects … or
effects of treatment versus no-treatment comparisons?” (Wampold et al., 1997, p.
Other studies, however, have raised questions about the Dodo bird effect. For
example, Dobson (1989) conducted a meta-analysis comparing cognitive therapy for
depression to a number of other standard treatments including pharmacotherapy and
other psychotherapies. Dobson concluded that cognitive therapy was superior to any
other treatment for depression (Dobson, 1989). Wampold et al.’s (1997) metaanalysis found that when comparing effect sizes across a number of disparate studies
one could argue that most psychotherapies were equivalent. Dobson’s meta-analysis
examined treatments for a specific disorder and in doing so the Dodo bird effect
The use of meta-analysis is not without controversy itself. Arguments have
been made that meta-analysis can be used to confirm a priori hypotheses. Some have
confirmed the Dodo bird effect by performing meta-analyses of meta-analyses
(Lipsey & Wilson, 1993), which prompted Hans Eysenck to respond:
A method that averages apples, lice, and killer whales (here psychological, educational, and
behavioral treatments) can hardly command scientific respect; there is little in common
among psychotherapy for bulimia, cognitive behavioral therapy with dysfunctional children,
parent effectiveness training, diversion programs for juvenile delinquents, effects of hypnosis
on anxiety, group assertion training, career education programs, social skills training,
preoperative preparation of children for surgery, biofeedback for migraine, music therapy for
pain reduction, adolescent pregnancy programs, behavioral treatment for obesity, the Feingold
diet for hyperactivity, computer-aided instruction, interactive video instruction, cooperative
learning, positive reinforcement in the classroom, enrichment programs, coaching for
Scholastic Aptitude Tests, creativity training techniques, Frostig visual perception training,
language intervention, science in-service training, career development courses, and mass
media campaigns. To combine the outcomes of all these (and many more) meta-analyses
seems to me a gigantic absurdity (Eysenck, 1995; see also Eysenck, 1994 for a critique of
Other critics have argued that the Dodo bird effect found via many published metaanalyses may be strongly influenced by other factors including unaccounted for
mediator and moderator variables (Shadish & Sweeney, 1991), or by inappropriate
treatment comparisons (Crits-Cristoph, 1997). Shadish and Sweeney (1991) argued
that therapy orientation does make a significant contribution to outcome through
mediating and moderating effects and that the Dodo bird effect is simply an artifact of
the failure to look for these effects (Shadish & Sweeney, 1991). They found that
mediator variables, such as level of standardization and implementation of treatment
in a study, and moderator variables, such as conducting a study in a university setting,
influenced outcome (Shadish & Sweeney, 1991). Critics of the early meta-analyses
(such as the classic Smith et al., 1980, study) assert that many of the studies used in
the analyses were conducted with participants who were not being treated for clinical
problems. For the studies that did focus on clinical problems, many of them were
conducted prior to the publication of the DSM-III (American Psychiatric Association,
1980), a watershed in the classification of psychological disorders. Lastly, critics
stress that the establishment of treatment manuals has revolutionized outcome
research, something not accounted for in the early meta-analyses (Task Force on
Promotion and Dissemination of Psychological Procedures [Task Force], 1995).
The Dodo bird controversy had the effect of convincing some to accept that
something about psychotherapy in general is effective, and that exploration and
integration of so-called “common factors” shared by most forms of psychotherapy
would be the most beneficial direction for the field. In fact, this interest in common
factors has lead to the development of organizations devoted to the study and
promotion of psychotherapy integration (e.g., Society for the Exploration of
Psychotherapy Integration). Others have concluded that although we now know that
psychotherapy is generally effective, we should continue to heed Paul’s call to arms
and focus on efficacy and effectiveness in outcome research for specific interventions
targeting specific problems.
1.2 The Empirically Supported Treatment (EST) Movement
As discussed above, over the past two decades treatment outcome research has
produced treatment manuals with demonstrated efficacy for a wide range of
problems. These empirically evaluated treatments have largely been developed and
tested by academics in clinical laboratory settings. This has spawned a debate over
the generalizability of efficacy research and a call by some for more effectiveness
research (e.g., Seligman, 1995). After the publication of a survey of its readers’
experiences with mental health services in Consumer Reports (1995), Martin
Seligman (who was involved with the development and implementation of the
survey) became a strong proponent of moving treatment outcome research from a
focus on efficacy (outcome studies under tightly controlled conditions using clearly
defined treatments with clearly defined population) to a focus on effectiveness
(outcome studies under loose, more “real-world” conditions). Seligman contended,
“the efficacy study is the wrong method for empirically validating psychotherapy as it
is actually done, because it omits too many crucial elements of what is done in the
field” (Seligman, 1995, p. 968). Seligman’s conclusions have been met with
skepticism by many in the academy, however, as illustrated by the following
quotation from leading psychotherapy researchers:
If the field of psychotherapy research were to adopt Seligman’s (1995) recommendation
uncritically and accept uncontrolled, self-selected consumer surveys–or anything less than the
most rigorous scientific standards–as a model for determining the benefits of treatments, it
would be taking a giant step away from the rest of medical research and its staggeringly
impressive accomplishments (Mintz, Drake, & Crits-Cristoph, 1995).
David Barlow (1996) summarized some of the objections to efficacy research. He
stated that one area of objection surrounds the notion that current applications of the
scientific method are inappropriate for psychotherapy research. Further, arguments
generally include the question of the adequacy or inadequacy of specific philosophies
of science that are applied in psychotherapy research. Barlow argued that one of the
major current factors in the push for empirical support for psychological interventions
is the demand being placed on health care professionals by government agencies and
healthcare policymakers to provide evidence that their treatments work. Thus,
external pressure to demonstrate efficacy supplants the field’s desire for philosophical
Another area of objection Barlow outlined involves questions raised by
applying highly structured research results and treatment manuals to frontline clinical
settings. Further, some argue that it is premature to identify certain treatments as
effective when it is unclear why they are effective (Barlow, 1996). In other words,
some argue that the active ingredients are inherent to all psychotherapy, not
something special about specific circumscribed treatments (a rehashing of the Dodo
bird argument). For example, Frank & Frank (1991) argued that common factors
such as the therapeutic relationship, setting, and rationale for therapy are at the core
of behavioral change. It should also be noted that some in the field have called for an
increase in “softer” research methodologies like clinical case studies and selfexperimentation to augment “practicing knowledge” (Howard, 1993).
1.3 The Creation of a Task Force
Cohen, Sargent, and Sechrest (1986) published an investigation of
professional psychologists’ utilization of psychotherapy research in the American
Psychologist. They found that 27% reported that empirical research had no
discernible impact on their clinical practice. Hence, based on their data, more than a
quarter of psychologists rely solely on other sources to inform their clinical work. It
is unclear to what extent empirical research plays a role in informing current
practicing psychologists’ choice of interventions. Psychotherapy outcome
researchers report growing frustration with the science-practice gap, while front-line
clinicians suffer from little time to wade through the morass of often-conflicting
research, not to mention the possible need for retraining. In part to address this
science-practice gap, a Task Force on Promotion and Dissemination of Psychological
Procedures was created within Division 12 (Clinical Psychology) of the American
Psychological Association. They issued a report in 1995 as “a response to intense
social, economic, and political forces that demanded to know which of the 400-plus
psychotherapies were effective” (Beutler, 1998). The Division 12 report (Task Force,
1995) was an attempt to provide a blueprint for what treatments have been shown to
be efficacious with what problems. The group described the rationale for the
development of a Task Force and their report:
This task force was constituted to consider methods for educating clinical psychologists, third
party payers, and the public about effective psychotherapies. Lacking the enormous
promotional budgets and sales staff of pharmaceutical companies, clinical psychologists labor
at a disadvantage to disseminate important findings about innovations in psychological
procedures. Despite the great strides in the development and validation of effective
treatments, it is not clear that the benefit of our approaches is widely appreciated, even by
other clinical psychologists (Task Force, 1995, p. 3).
The work of the Task force has sparked significant controversy and debate, and has
brought to the forefront a variety of issues. For example, epistemological
disagreement on the question of determining what works (e.g., empirical evaluation
vs. clinical experience) is likely the nucleus of the debate. In addition to the
previously mentioned criticism of efficacy research, the use of practice guidelines and
treatment manuals are viewed by some clinicians as overly constraining due to being
limited to particular therapeutic approaches. Further, some argue that disorderfocused practice guidelines and treatment manuals oversimplify the complex nature
of clients seen outside of treatment research. Further, the criteria for defining
“empirical support” have generated considerable debate (Herbert, 2000). Several
psychology journals have devoted special issues to this topic (e.g., Herbert, 2003). In
light of this controversy, it remains unclear to what degree clinical practice has been
affected by this push towards the use of empirically validated interventions.
In addition to the numerous new treatments being developed and tested for
specific disorders, traditional, non-empirically supported psychotherapies (e.g.,
psychoanalytic psychotherapy) continue in wide popularity. Moreover, novel
treatments continue to be developed at a relatively rapid rate. Practicing clinicians
generally develop these treatments, most with little regard for current psychotherapy
theory and with little emphasis on scientific evaluation. Thus, treatment approaches
that have not undergone rigorous empirical evaluation enjoy widespread use. Many
clinicians often use the aforementioned argument that psychotherapy, and what is
effective about it, cannot be captured in a laboratory setting, thereby rendering useless
the findings of psychotherapy research.
1.4 Innovative Therapies
Complementary and Alternative Medicine (CAM) includes such a variety of
theoretical frameworks and treatments that it is difficult to define. Generally, CAM
includes therapies that have been developed outside of the realm of mainstream
science, that incorporate religious or spiritual ideas, and that have not been subjected
to rigorous empirical validation. As medicine has witnessed a boon in CAM, so has
mental health practice. For example, in a recent article in the APA journal
Professional Psychology: Research and Practice, White (2000) recommends that
professional psychologists integrate CAM into their practices. Citing her advanced
training in Oriental medicine and homeopathy, White provides a blueprint for how
CAM can be incorporated into private practice as “integrative medical psychology.”
She describes her own such practice as including offices dedicated to acupuncture and
natural medicine as well as an herbal apothecary, all in addition to her psychotherapy
Interlaced with CAM, new forms of psychotherapy seem to mushroom in the
field of mental health treatment on an almost daily basis. Often labeled as
“innovative” or “cutting-edge,” these approaches generally do not follow the standard
path of theoretical development, empirical evaluation, and dissemination through
publication in peer-reviewed journals. Instead, these techniques are frequently
developed based on clinical observation, supported using anecdotal evidence and
testimonials, and promoted through workshops, training media (i.e., audio- and
videotapes, books), and increasingly through websites on the Internet.
Over the past decade the most popular and widely utilized genre of
“innovative” techniques has been the Power/Energy Therapies (P/ET’s). Power
therapies are so-called because practitioners and promoters argue that they are
significantly more powerful and rapid than traditional treatment approaches
(Commons, 2000). The energy therapies are so-called because they generally
incorporate traditional Eastern philosophies about energy systems in the body. They
are typically lumped together because most energy therapies are considered power
therapies; on the other hand not all power therapies are considered energy therapies as
in the case of Eye Movement Desensitization and Reprocessing (EMDR; Shapiro,
1995). Some examples of the P/ET’s, in addition to EMDR, include Thought Field
Therapy (TFT; Callahan, 1985), Emotional Freedom Techniques (EFT; Craig, 2001),
Visio/Kinesthetic Dissociation (V/KD; Bandler, 1985), Traumatic Incident Reduction
(TIR; Gerbode, 1995), Touch and Breathe (TAB; Diepold, 2000), Be Set Free Fast
(BSFF; Nims, 2001), Tapas Acupressure Technique (TAT; Fleming, 1999), and
Emotional Diagnostic and Treatment Methods (EdxTM; Gallo, 2000). This is not an
exhaustive list. A thorough overview of each of the many P/ET’s is beyond the scope
of this paper. However, the two most archetypal representations of P/ET’s, and
almost certainly the currently most popular, will be discussed: EMDR and TFT.
1.5 Eye Movement Desensitization and Reprocessing (EMDR)
Developed by clinical psychologist Francine Shapiro, EMDR is arguably the
most popular and controversial of the Power/Energy therapies. EMDR is based on a
rather crude theory that emotional disturbances become “trapped” in the brain and
that different forms of stimulation, like side-to-side eye movements, provoke the
brain’s “information-processing system,” thereby allowing the brain to heal. The
EMDR Institute website claims that since its development in 1987, over 50,000
licensed mental health professionals have been trained in EMDR and that EMDR has
“successfully helped over a million individuals” (EMDRIA, 2003). EMDR also
distinguishes itself from the rest of the P/ET’s, as there is a substantial body of
research investigating its effects. EMDR has not been demonstrated to be superior to
extant treatments for emotional trauma and has in some cases been shown to be
inferior (Herbert et al., 2000; Davidson & Parker, 2001; Devilly, 2002). Critics of
EMDR have argued that the eye movements are superfluous to any observed
treatment effects (Lohr, Tolin, Lilienfeld, 1998) and therefore because of the
similarities with standard cognitive behavioral techniques “what is effective in
EMDR is not new, and what is new is not effective” (Rosen, Lohr, McNally, &
Herbert, 1999, p.10). Although EMDR was created as a treatment for emotional
trauma, proponents have applied it to a wide variety of problems. Further, critics
argue that the popularity of EMDR has far surpassed the empirical evidence
supporting it (Herbert et al., 2000; Herbert, in press).
1.6 Thought Field Therapy (TFT)
As EMDR is the standout of the broad category of Power therapies, TFT is the
prototype of the subcategory of Energy therapies. Developed and promoted by
psychologist Roger Callahan, TFT is based on the notion that the human body
possesses invisible energy fields called “thought fields.” Psychological distress is the
result of disruptions -- what Callahan has termed “perturbations” -- occurring in the
flow of these energy fields. These energy flow disruptions are treated by physically
tapping on “energy meridian” points in specific patterns (“algorithms”) specific to the
presenting problem, while thinking about the traumatic event or negative feelings.
Thus, “when applied to problems TFT addresses their fundamental causes, balancing
the body's energy system and allowing you to eliminate most negative emotions
within minutes and promote the body's own healing ability” (TFTRX, 2001).
Proponents consistently assert that TFT is able to “cure” myriad problems; “it gives
immediate relief for PTSD, addictions, phobias, fears and anxieties” (Thought Field
Therapy Training Center of La Jolla, 2001). Despite proponents’ extraordinary
claims, critics note that there is no compelling empirical evidence that TFT is
effective for any psychological problems. Further, the purported theoretical
foundation for TFT is “grounded in unsupported and discredited concepts” (Gaudiano
& Herbert, 2000). Several of the other PE/T’s are offshoots of TFT, often based on
the same theoretical underpinnings and/or developed by individuals trained in TFT.
This includes EFT, which in turn is incorporated into other P/ET’s like GTT and
One likely reason for the popularity of P/ET’s is that they are aggressively and
effectively marketed directly to clinicians, while EST’s are disseminated through the
often-glacial peer-review process into a multitude of scientific journals. In
competition with one another, advances made in EST’s appear to be frequently
overshadowed by the promotional savvy of the supporters of the P/ET’s. A typical
marketing technique of many if not most of the P/ET’s is to provide a certification
program in which individuals pay money to receive training. These individuals are
then certified in this treatment approach, receive a handsome diploma, and are able to
add concocted strings of letters to the end of their names. This process leads the
public to think that these certifications were provided by a higher, socially approved
agency (Singer & Lalich, 1996).
As previously mentioned, the P/ET’s are not without critics. Behavior therapy
pioneer Arnold Lazarus opined on the current state of psychotherapy (2000):
The most unfortunate development, in my opinion, is the vast augmentation of New Age
Therapists who adhere to mystical and transpersonal philosophies. Added to this are the socalled Power Therapies that have attracted militant adherents (such as the promulgators of
Thought Field Therapy whose basic assumptions rely on energy fields that have no scientific
validity)” (p.154).
Critic Tana Dineen argued that professional psychology is taking on many of the
characteristics of a religion evidenced by “the adoption of Eastern mystical and
Native American approaches as healing techniques in psychotherapy” and the “the
acceptance of spiritual, transcendental, and supernatural concepts into the language of
psychotherapy” (Dineen, 1998).
Although it is currently unclear to what magnitude P/ET’s are utilized by
psychologists, there is little doubt that their rate of growth is increasing rapidly. The
tension between scientific and non-scientific approaches to psychotherapy and the
rise of P/ET’s may be better understood in the context of theoretical orientation.
1.7 Theoretical Orientation
There is much overlap between theoretical orientation and practical
orientation. The meaning of the term “theoretical orientation” can range from very
abstract philosophical positions on ontology and epistemology to very concrete
definitions that describe clinicians’ day-to-day practical interaction with clients. In
other words, theoretical orientation in one instance may refer to someone’s general
worldview about the nature of psychopathology and its manifestations. In another
instance it may reflect whether someone chooses supportive listening versus
systematic desensitization to treat individuals with phobias. This broad range is
reflected in the literature. This range is a reflection of the continuum of specificity,
rather than a natural dichotomy.
The present study will focus more on the topographical features of orientation
than the philosophical features. This study will continue the tradition of using the
term theoretical orientation, with a potentially more accurate term for the focus of this
study being practical orientation. But it is first necessary to provide a brief overview
of the previous research on theoretical orientation.
1.8 Prevalence of Theoretical Orientations and Problems with Eclecticism
A number of studies have attempted to estimate the popularity of various
theoretical orientations among professional psychologists. For example, Jensen,
Bergin, & Greaves (1990) found that 70% of clinical psychologists surveyed reported
being “eclectic” in their theoretical orientation. They also provided an overview of
similar survey research conducted previously and found that their sample was the
highest percentage reporting an “eclectic” orientation to date. They broke down the
eclectic group further by having those that identified themselves as eclectic list
combinations of orientations. The top four theoretical preferences among those that
referred to themselves as eclectic were: cognitive (63%), dynamic (62%), behavioral
(56%), and humanistic (32%) (Jensen, Bergin, & Greaves (1990).
Milan, Montgomery, & Rogers (1994) attempted to conduct an empirical
investigation of various claims that had been made regarding paradigmatic shifts and
trends (e.g., the growth of eclecticism, the decline of behaviorism, a resurgence of
psychoanalysis). The results of their data analyses demonstrated some weak trends
in theoretical orientation in the decade of the 1980’s. Their general conclusion was
that there was some growth in the cognitive perspective while behavioral,
interpersonal, and psychoanalytic orientations all remained strong, but there was
mostly little change when measured from the beginning to the end of the decade.
They also found that the most common theoretical orientation the respondents
endorsed was “eclectic” with 43.3, 42.7, and 39.1 percent of respondents endorsing
this as their primary theoretical orientation from years 1981, 1985, and 1989,
respectively. All of their data were obtained from the National Register of Health
Service Providers in Psychology from 1981, 1985, and 1989 (Council for the National
Register of Health Service Providers in Psychology, 1981; 1985; 1989).
A clear problem with prior research investigating theoretical orientation has
been the label eclectic. Lazarus and Beutler (1993) provide an overview of the two
main eclectic camps. They describe “unsystematic eclectics” and “theoretical
integrationists” as those who attempt to blend the various components of theories into
a coherent whole. They describe “technical eclectics” as those who “select
procedures from different sources without necessarily subscribing to the theories that
spawned them… Hence, they borrow techniques from other orientations, based on the
proven worth of these procedures” (Lazarus & Beutler, 1993). Thus, in keeping with
the EST movement, technical eclectics provide therapeutic techniques with empirical
support whereas unsystematic eclectics and theoretical integrationists are more
interested in the integration of different schools at a theoretical level.
Although different definitions exist, previous research focusing on theoretical
orientation has failed to distinguish theoretical and technical eclecticism. In other
words, previous research with those describing themselves as eclectic focused on
what theories clinicians’ subscribe to and not what techniques they utilize. The
present study will attempt to resolve this issue by distinguishing between and
addressing both theoretical and technical eclecticism.
1.9 Predicting Theoretical Orientation
Previous research has attempted to elucidate some of the factors associated
with theoretical orientation. This section will summarize some of the research
focusing on both psychology graduate students and practicing psychologists.
Graduate Training. Perhaps the most obvious predictor of a psychologist’s
theoretical orientation would be what they learned in graduate school. However, in a
sample of professional psychologists the theoretical orientation of their most
influential mentor in graduate school was compared to their own current theoretical
orientation. This demonstrated only moderate correlation. Further, more than half of
professional psychologists surveyed reported a different theoretical orientation than
their former professors (Sammons & Gravitz, 1990).
Self-Monitoring. This study found that using a standard measure of selfmonitoring (i.e., one’s ability to adjust one’s behavior in response to external cues),
high self-monitors (i.e., those better able to adjust their behavior to people and
situations) were more eclectic than low self-monitors and that those frequently using
more than one orientation had higher self-monitoring scores. Furthermore, selfmonitoring correlated negatively with psychoanalytic endorsement, but in a positive
direction with behavioral, systems and eclectic endorsements. It should be noted that
the sample used in this study consisted of intake interviewers in a child guidance
center with education level ranging from a bachelors to a doctorate degree (Mathews
& Marshall, 1988).
Mental Health Values. Jensen & Bergen (1988), using a mail survey,
examined clinicians’ “mental health values themes” and found an effect for
theoretical orientation. Participants rated these themes, which were made up of
statements like “Develop effective strategies to cope with stress” and “Be open,
genuine, and honest with others”, on a Likert scale of how important they felt they
were for the maintenance of a positive, healthy lifestyle. Themes that were associated
with theoretical orientation included a forgiveness theme “Forgive others who have
inflicted disturbance in oneself” and “Make restitution for one’s negative influence.”
They found that those who described themselves as psychodynamic agreed less
strongly with this theme than did systems, behavioral, or eclectic clinicians. They
also found that behavioral and systems-oriented therapists expressed lower agreement
than psychodynamic and eclectic therapists with the self awareness/growth theme
(e.g., Become aware of inner potential and ability to grow; Discipline oneself for the
sake of growth) (Jensen & Bergen, 1988). Their sample included psychologists,
psychiatrists, marriage and family therapists, and social workers.
Ethical Decision Making Skills. Haas, Malouf, & Mayerson (1988) examined
ethical decision making skills in psychologists. They sent out surveys that featured
10 clinical case vignettes that presented ethical dilemmas. They did not find any
meaningful differences across theoretical orientations. However, the study employed
a limited, forced choice for theoretical orientation (Haas, Malouf, & Mayerson,
Clinical vs. Counseling Psychologists. Zook and Walton (1989) attempted to
address the recent debate in the literature involving proposals by some (e.g., Levy,
1984) that because there is so much overlap between clinical, counseling, and school
psychology that they be merged into a broader "human services psychology." Zook
and Walton conducted a survey of clinical and counseling psychologists examining
theoretical orientation and work place setting. Theoretical orientation was broken
down into three main categories based on participant’s responses: psychodynamic
(dynamic and analytic), humanistic (existential, gestalt, person-centered,
transactional-analysis), and behavioral (cognitive-behavioral, behavioral, rationalemotive).
Seventy-five percent of the sample chose more than one orientation.
Grouping counseling and clinical psychologists together, 24.2% fell into the
psychodynamic category, 29% in the humanistic category, and 36.8% in the
behavioral category. The three most endorsed orientations when including the
subcategories were cognitive-behavioral (20.2%), humanistic (18.5%), and
psychodynamic (18%). They also found that younger clinical psychologists tended
not to favor the psychodynamic orientation, leading the authors to conclude that
either these individuals will later come to embrace the orientation or that there is a
move away from it (Zook & Walton, 1989).
Another survey study of clinical and counseling psychologists conducted by
Johnson and Brems (1991) attempted to address some of the shortcomings of the
Zook and Walton (1989) study, namely the non-objective measure of theoretical
orientation. To speak to this, they employed the Theoretical Orientation Scale (TOS;
Coan, 1979). The TOS is a 63-item instrument where respondents select from a 5point Likert scale (1= strongly disagree to 5 = strongly agree). The items are drawn
from eight primary factors that tap theoretical content such as behavioral versus
experiential content emphasis and impersonal causality versus personal will. One
major problem with the TOS is that it provides little information about what specific
interventions clinicians employ. Hence, it provides information about more abstract
theoretical orientation but not practical orientation. The study found no difference
between counseling and clinical psychologists using the TOS.
Family of Origin. In their survey of psychologists, Johnson, Campbell, &
Masters (1992) found that several family of origin characteristics demonstrated weak
correlation with theoretical orientation as measured by the Theoretical Orientation
Survey (TOS). Range of feelings, empathy, and openness to others were the item
areas that were found to have the strongest relationship with theoretical orientation. It
is important to note that theoretical orientation in this study is defined by the TOS
and not by a specific treatment approach (Johnson, Campbell, & Masters, 1992).
Personality Factors. Utilizing an assessment of the Five-Factor Model of
personality, Scandell, Wlazelek, & Scandell (1997) examined personality factors and
theoretical orientation. Theoretical orientation was measured by asking the
participants to rate their belief in and adherence to a list of common orientations.
They found that the cognitive orientation was positively correlated with the
agreeableness domain and the related facets of straightforwardness and altruism.
Humanistic orientation was correlated with openness to fantasy and openness to
action. The Gestalt orientation was correlated with openness to fantasy (Scandell,
Wlazelek, & Scandell, 1997). This study was hampered by a number of major
methodological problems, however, including basing results on a small convenience
In summary, a number of studies have attempted to explain factors that
contribute to clinicians’ theoretical orientation. However, this research has failed to
provide a complete picture of the factors that contribute to the development of
theoretical orientation. Further, no research has examined theoretical orientation
when it is defined as the specific treatments clinicians’ employ. With the movement
towards empirically supported treatments coinciding with a rise in questionable
Power and Energy therapies, we know very little about factors that lead some
clinicians to chose EST’s and some to chose PE/T’s or other interventions lacking
empirical support. Critical thinking skills may be a factor when clinicians’ are faced
with making a decision about what treatments they will use. For example, it is
possible that an individual who is strong in evaluating arguments (a critical thinking
skill) is less likely to accept anecdotal evidence as supportive of a novel
1.10 Critical Thinking
Critical thinking can be difficult to define operationally. Many definitions of
critical thinking have been suggested with these definitions being informed from
education, philosophy, and psychology (Sormunen & Chalupa, 1994). However,
there are important themes running through most accepted definitions. For the
purposes of this study we will adopt the definition of critical thinking from Levy
(1997): “an active and systematic cognitive strategy to examine, evaluate, and
understand events, solve problems, and make decisions on the basis of sound
reasoning and valid evidence” (p. 236). Additionally, Klaczynski, Gordon, and Fauth
(1997) submit that many in the field view critical thinking as being composed of two
The first factor is the ability that is principally reflected in the above definition
of critical thinking. This factor represents competency in actively performing a
cognitive process (e.g., problem solving). The second factor involves the
metacognitive process of evaluating evidence that may challenge one’s beliefs or
goals (Klaczynski, Gordon, & Fauth, 1997). In other words, a critical thinker is able
to evaluate the influence that their existing beliefs have on their ability to reason.
Further, they are able to partial out the influence of their beliefs on their ability to
think critically. In summary, a critical thinker not only possesses the appropriate
skills to think critically, they possess the knowledge and ability to use them in
varying conditions (e.g., when evidence conflicts with held beliefs).
1.11 Critical Thinking Skills
Halpern (1998) proposed a helpful taxonomy of critical thinking skills that
includes the following areas: (a) verbal reasoning skills. These include skills that one
uses to comprehend and defend against persuasive techniques that are embedded in
language; (b) argument analysis skills. An argument is a set of statements with at
least one conclusion and one reason that supports this conclusion. In real life,
arguments are often complex, with reasons that run counter to the conclusion, stated
and unstated assumptions, irrelevant information, and intermediate steps; (c) skills in
thinking as hypothesis testing. People function like intuitive scientists to explain,
predict, and control events. These skills include generalizability, recognition of the
need for an adequately large sample sizes, and validity; (d) likelihood and
uncertainty. Because very few events in life can be known with certainty, decisions
should be informed with the correct use of cumulative, exclusive, and contingent
probabilities; (e) decision-making and problem-solving skills. Generally, all critical
thinking skills are used to make decisions and solve problems, but the skills included
in this category involve generating and selecting alternatives and judging among
them. Creative thinking skills are subsumed under this category. Halpern suggests
that collectively these five categories, sometimes referred to as macroabilities,
represent a working model of the skills approach to critical thinking (Halpern, 1998).
Halpern’s model of the skills approach to critical thinking is structured in part to be
used for the teaching of these skills (Halpern, 1998).
1.12 Measures of Critical Thinking Skills
There are a number of instruments that have been developed to measure
critical thinking skills. Two of the most widely used and studied instruments are the
Watson-Glaser Critical Thinking Appraisal (WGCTA; Watson & Glaser, 1980) and
the Cornell Critical Thinking Test (CCTT; Ennis, Millman, & Tomko, 1985).
Consistent with Halpern’s general critical thinking skills taxonomy (1998), the
WGCTA and CCTT pinpoint specific skill areas. Although there is not a direct oneto-one correspondence between the specific subscales of the WGCTA and the CCTT,
the subscales do appear to tap very similar skill domains. Moreover, both scales are
generally consistent with Halpern’s model. Although measures of critical thinking
correlate with a number of other psychological constructs (e.g., IQ), they appear to
represent a distinct (Watson & Glaser, 1994) yet heterogeneous construct (Ennis,
Millman, & Tomko, 1985). For example, significant correlations have been
identified between the WGCTA and the Otis-Lennon Mental Ability Tests-Gamma
(r=.60) and the WGCTA and the Wechsler Adult Intelligence Scale-Verbal (r=.55).
Based on these correlations, the WGCTA appears to tap a construct that is related to
but not fully accounted for by general intellectual ability as measured by standard
intellectual measures (Watson & Glaser, 1994).
The Watson-Glaser Critical Thinking Appraisal (WGCTA). The WatsonGlaser Critical Thinking Appraisal (WGCTA) is a widely used measure with wellestablished psychometric properties. The WGCTA has three separate forms; A, B,
and S. Forms A and B (WGCTA-A; WGCTA-B; Watson & Glaser, 1980) were the
earliest manifestations of the test and feature the same number of items and the same
5 subareas. The two forms are frequently used as a pretest and posttest to prevent
possible practice effects if the same test is administered twice. Form S (WGCTA-S;
Watson & Glaser, 1994) is a newer short version of form A. Form S maintains the
same format as form A but has had the number of questions reduced by half to allow
for the test to be administered in half the time. All three tests are appropriate for
individuals with at least a ninth-grade education (Watson & Glaser, 1994). In an
evaluation of the psychometric properties of Form S, Loo and Thorpe (1999)
identified several problems including poor recovery of the five subtests in factor
analyses and low internal-consistency reliabilities for the scores on the five subscales.
However, they found the test to be free of gender effects, and recommended its use
(Loo & Thorpe, 1999).
The WGCTA is based on abilities originally identified by Dressel and
Mayhew (1954): (a) definition of a problem, (b) selection of significant information
for the solution of a problem, (c) recognition of assumptions (stated or not stated),
(d) formulation and selection of hypotheses, (e) validation of conclusions, and (f)
judgment of inferences (Dressel & Mayhew, 1954). Based on these abilities, the
WGCTA is designed to measure five subareas of critical thinking that, as a
composite, provide an overall assessment of critical thinking ability.
The first area is inference, which is defined as “discriminating among degrees
of truth or falsity of inferences drawn from given data.” The second area is
recognition of assumptions, which is defined as “recognizing unstated assumptions or
presuppositions in given statements or assertions.” The third area is deduction, which
is defined as “determining whether certain conclusions necessarily follow from
information in given statements or premises.” The fourth area is interpretation, which
is defined as “weighing evidence and deciding if generalizations or conclusions based
on the given data are warranted.” The last area is evaluation of arguments and is
defined as “distinguishing between arguments that are strong and relevant and those
that are weak or irrelevant to a particular question at issue” (Watson & Glaser, 1994,
pp. 9-10).
Each of the abovementioned subareas is measured in a respective subtest of
the WGCTA: (a) Inference, (b) Recognition of Assumptions, (c) Deduction, (d)
Interpretation, and (e) Evaluation of Arguments. In each of the subtests, the
examinee reads brief passages or scenarios that reflect real-world problems,
statements, arguments, and interpretations. The examinee then responds to several
items for each passage or scenario. The scenarios can fall into two categories: neutral
and controversial. For example, neutral scenarios entail subject matter that people do
not generally have strong feelings or prejudices about (e.g., the weather). The
controversial scenarios include content about politics and social issues that people
often do have strong feelings about. The controversial-content scenarios are effective
in tapping into the examinee’s ability to think and evaluate evidence that may
challenge their beliefs (the second component of a skills approach mentioned above).
Again, a skill in critical thinking is to override opinions, attitudes, and biases that may
affect a correct response (Watson & Glaser, 1994; Sa, West, & Stanovich, 1999).
The Cornell Critical Thinking Test (CCTT). The Cornell Critical Thinking
Test (CCTT; Ennis, Millman, & Tomko, 1985) is also a widely used measure of
critical thinking with acceptable reliability, internal consistency, and validity. The
CCTT features two separate tests, Level X and Level Y. Level X is designed for
students in grades 4 through early college. Level Z targets advanced and gifted high
school students, college students, and other adults. The CCTT is designed to be a
“general critical thinking skills test” as it covers critical thinking as a whole. Both
tests feature multiple-choice items, each with three choices and one correct answer.
Level X has 71 items and Level Z has 52 items. An evaluation of the psychometric
properties of the CCTT Level X and WGCTA Form YM based on the 10 essential
validity standards and the 5 essential reliability and measurement error standards
from the Standards for Educational and Psychological Tests (APA, 1985) indicated
that the measures met the standards between the levels of "minimal" or "somewhat"
(Modjeski & Michael, 1983).
Ennis, Millman, and Tomko (1985) used the following working definition of
critical thinking in the development of the CCTT: “Critical thinking is the process of
reasonably deciding what to believe and do” (p.1). The authors note that there are
numerous ways to subcategorize critical thinking including an approach that
examines three types of inferences to beliefs (induction, deduction, and evaluation)
and four types of bases for such inferences: the results of other inferences;
observations; statements made by others; and assumptions. They further stress that
close attention must be made to meaning in dealing with the three types of inferences
and four types of bases. From this model of categorization, they conclude that a test
of general critical thinking might cover induction, deduction, evaluation, observation,
credibility (of statements made by others), assumption identification, and meaning.
Lastly, they suggest that an ideal test of general critical thinking skills would include
“attitudes” of a critical thinker such as open-mindedness, caution, and valuing being
well-informed, but they do not directly test for these components because of the
difficulty in doing so. Thus, the aspects of critical thinking incorporated into the
CCTT are induction, deduction, observation, credibility, assumptions, and meaning
(Ennis, Millman, & Tomko, 1985). Operational definitions are not included for these
aspects, but these can be gleaned from the literature from which they are derived.
Using Halpern’s (1998) general critical thinking skills taxonomy, the
WGCTA and CCTT provide items designed to measure specific skill areas. These
two measures were reviewed for two reasons. First, they are the two most widely
validated and utilized critical thinking assessment devices (Watson & Glaser, 1980;
1994; Ennis, Millman, & Tomko, 1985). Secondly, they have strong overlap in
content area. In other words, both assessments are designed to measure extremely
similar subareas of critical thinking that, when taken together, provide a composite of
critical thinking.
1.13 Critical Thinking in the Health Care Professions
If we paraphrase Ennis, Millman, & Tomko’s (1985) brief definition of
critical thinking as the process of reasonably deciding what to believe or do, it is clear
that this is an important function for all health care providers. Professionals are often
faced with limited information and time constraints and forced to make decisions that
are sometimes literally life or death. Because of this, critical thinking is recognized
as an integral part of many healthcare professionals’ education and training. For
example, the Council of Baccalaureate and Higher Degree Programs designate critical
thinking as a required outcome criterion for the National League for Nursing
accreditation process (Adams, Whitlow, Stover, & Johnson, 1996).
Critical thinking skills are frequently assessed as an outcome measure after
courses designed to teach these skills in medical and nursing schools. There is a large
body of literature on teaching and measuring critical thinking skills from the field of
nursing. Much of this literature illustrates the role of critical thinking in nursing
activities (e.g., Boychuck, 1999), teaching critical thinking to nursing students (e.g.,
Carter & Gentry, 2000) or the use of critical thinking measures to assess the learning
of critical thinking skills in students (e.g., Frye, Alfred, & Campbell, 1999).
Critical thinking is also a frequently discussed subject in physician training.
Scott and Markert (1994) tested critical thinking skills in medical students using the
Watson-Glaser Critical Thinking Appraisal and found that critical thinking skills
correlated with student academic success in the first two years of medical school and
with MCAT scores. They concluded that critical thinking skills are one factor
involved in a student’s success in the first two years of medical school (Scott &
Markert, 1994).
1.14 Critical Thinking Skills in Professional Psychology
Very little research has examined critical thinking skills per se among
psychologists or psychology students. Some have warned of the inherent danger of
“common sense” to psychologists as a possible enemy of critical thinking (Fletcher,
1984). Some empirical research has found that German female psychologists rated
significantly higher than a group of control professionals on criteria of “wisdom-
related knowledge” (Smith, Stuadinger, & Baltes, 1994). However, no research has
been conducted examining critical thinking in professional psychologists.
One study by Roe (1999) conducted with psychology students examined
whether believers in the paranormal differed in terms of critical thinking as compared
to non-believers. The author reports that no significant difference was found, but it
should be noted that critical thinking was not measured using a standardized
assessment but rather through subjects’ written evaluation of a paranormal study and
their assignment of a Likert scale score of the overall quality of the study (Roe,
1.15 Heuristics and Biases
Research on judgment under uncertainty, which has come to be known as the
heuristics and biases approach (Kahneman, Slovic, & Tversky, 1982), has attempted
to identify specific mental operations that affect intuitive predictions and judgments.
Some research has examined the role of heuristics and biases in psychologists’
decision making. For example, Garb (1996) found that the representativeness
heuristic was descriptive of clinicians’ cognitive processes when making clinical
diagnoses. The representativeness heuristic involves judging something by intuitively
comparing it to a prototype or a mental representation of a category (Myers, 1996).
Garb concluded that when the representativeness heuristic was a factor in the decision
making process that it can be inferred that the clinician was not attending to base rates
(Garb, 1996). In fact, individuals’ tendency to use or misuse base-rate information is
commonly found in the literature on cognitive heuristics and biases (Stanovich &
West, 1998).
Base-rate information refers to the rate or occurrence of a phenomenon within
a given population. There are two forms by which base-rate use is described in the
literature: base-rate neglect and base-rate fallacy. Base-rate neglect refers to
situations in which an individual does not use base-rate information when making a
decision, but does not imply whether the base-rate information should have been
used. On the other hand, base-rate fallacy implies that base-rate information was
ignored when it should have been used in the decision-making process (Gigerenzer,
Hell, & Blank, 1988). Other definitions describe base-rate neglect as attending more
to the hit rate (the representativeness) than the base-rate (Fiedler, Brinkmann, Betsch,
& Wild, 2000). For example, one might accord an anecdote (a co-worker’s negative
experience with a car) and base-rate data (outstanding review and large survey in
Consumer Reports) equal weight. In this example the base-rate information that a
large sample of people are pleased with the product is underused when it is given
equal weight to a single anecdote. When we ignore or underuse relevant base-rate
information, we are more likely to make errors in judgment.
No previous research has examined psychologists’ actual skill level in making
decisions. One potential factor in theoretical orientation/choice of therapeutic
interventions is clinicians’ critical thinking skills. This is the first study to examine
theoretical orientation by using a proxy system in which clinicians endorse actual
treatment approaches and techniques that they use. Although some have called for
“instruction in critical thinking in graduate-level classrooms” to help “stem the rising
tide of pseudoscientific treatments” (Kalal, 1999, p. 83), this is the first study to
examine critical thinking skills in psychologists.
The purposes of this study were as follows: 1) To examine the relative
frequency of use of various psychotherapeutic approaches associated with the major
theoretical orientations in professional psychology; 2) To obtain descriptive
information on the critical thinking skills of practicing psychologists; 3) To obtain
data on professional psychologists’ utilization of Power/Energy Therapy techniques;
4) To examine the relationship between psychologists’ self-described theoretical
orientation and their self-reported practical orientation or use of specific techniques
and approaches derived from the major theoretical orientations and; 5) To examine
whether a relationship exists between psychologists’ critical thinking skills and
practical/theoretical orientation, as well as their use of Power/Energy techniques.
Professional psychologists were surveyed regarding their practical/theoretical
orientation. Further, they completed an assessment of critical thinking skills designed
specifically for this study. It was hypothesized that critical thinking skills would
influence psychologists’ decisions about what treatment approaches to provide to
their clients. Thus, psychologists with relatively weak critical thinking skills would
be more prone to adopt treatment approaches that tend not to be developed within a
scientific framework, and that are based on scientifically questionable theories. In
particular, it is hypothesized that psychologists that utilize Power/Energy Therapy
techniques will have lower scores on the assessment of critical thinking when
compared to those that do not use these techniques.
2.1 Participants
Participation was solicited from the following APA divisions: 21 Fellows and
146 Members of Division 12 (Clinical Psychology), 17 Fellows and 150 Members of
Division 29 (Psychotherapy), and 3 Fellows and 164 Members of Division 42(Psychologists in Independent Practice). Participants were chosen from the APA
Membership Directory through the use of a systematic sampling technique. Selection
began at the member number matching a number selected from a random numbers
table. From this starting point, subjects were chosen based on total number of
members in the division divided by 100. For example, every 30th member of Division
12 was selected and every 13th member of Division 17 was selected. 80 packets were
also mailed to members of the Association for Comprehensive Energy Psychology
(ACEP). ACEP members were selected from the member directory available on its
Internet web site (, 2003). In an effort to send packets to
ACEP members that are practicing psychologists, those that listed credentials other
than a master’s degree (i.e., M.A., M.S., or M.Ed) or doctorate (i.e., Ph.D., Psy.D., or
Ed.D) were excluded. Thus, individuals reporting M.S.W., M.D., or other nonpsychology degrees, those that reported a bachelors as the highest degree, and those
that did not list their highest degree were all excluded. The groups (ACEP and APA
divisions) were selected in an attempt to obtain a diverse sample with respect to
practice orientation.
2.2 Procedure
Participants were sent via post a research questionnaire packet and asked to
complete the enclosed demographic form and questionnaires and return them in the
provided self-addressed-stamped envelope. The entire questionnaire packet required
no more than 25-30 minutes to complete. Total survey response rates based on
previous studies of randomly selected samples of clinical and counseling
psychologists have varied considerably. Zook and Walton (1989) received an
unusually high response rate of 66.5% in their study of theoretical orientation and
work setting. They sent the survey followed by a reminder postcard 30 days later to
non-responders. Thirty days after the postcard was sent they mailed another survey to
those who still had not responded. Finally, 30 days later a third survey was sent to
those who had still not responded. Haas, Maylouf, and Mayerson (1988) received
59% of surveys back of those mailed to members of APA’s Division of
Psychotherapy. Their study involved responding to 10 ethical dilemma vignettes.
Allison, Echemendia, Crawford, & Robinson (1996) achieved a return rate of 49%
from a single mailing in their study of psychologists’ training and work experience
with clients from diverse groups. Johnson & Brems (1991) likewise achieved a 49%
response rate based on an initial and a follow-up mailing in their study of
psychologists’ theoretical orientation. Polusny & Follette (1996) surveyed
psychologists’ attitudes and beliefs about Child Sexual Abuse (CSA) that included
questions about the participant’s own history of sexual abuse. Despite their low 22%
response rate, they were able to demonstrate that the sample was representative of the
APA membership population by comparing reported demographic information to a
directory survey compiled by the Office of Demographic, Employment, and
Educational Research (APA, 1993). Thus, the response rate for the present study was
anticipated to range from 22%-66.5%. However, safeguards employed in previous
studies (e.g., reminder postcards) were not used because of anonymity requirements
imposed by the Drexel University Institutional Review Board (IRB). Further, no
incentives were offered because of these strict confidentiality requirements.
2.3 Instrumentation
Each participant was mailed a research protocol packet consisting of a cover
letter, demographics sheet, Critical Thinking Questionnaire (CTQ), Treatment
Approaches and Techniques Questionnaire (TATQ), and a self-addressed-stamped
Cover letter. The cover letter provided a brief description of the study and
directions to complete the enclosed demographic sheet and questionnaires and return
them in the self-addressed-stamped envelope within four weeks.
Demographics Form. This form was used to request the following
information: age, gender, years since graduation, years of therapy experience, weekly
hours spent in therapy provision, highest degree, work setting, and theoretical
orientation. The following were forced choice items: gender (male, female), degree
(M.A./M.S./M.S.W., Ph.D., Ed.D., Psy.D., or other please specify), work setting
(academic, agency, or independent practice), and theoretical orientation
(Systems/Family Systems, Cognitive-Behavioral, Psychoanalytic/Dynamic,
Power/Energy, Existential/Humanistic/Phenomenological, Radical
Behavioral/Applied Behavior Analytic, and Eclectic). The work setting items were
derived from Zook and Walton (1989). See Appendix A for demographics form.
Critical Thinking Questionnaire (CTQ). The Critical Thinking Questionnaire
is a theoretically derived measure that was created for the purposes of this study
(Appendix B). The questionnaire consists of items based on several established
measures of critical thinking and several published studies of critical thinking. The
sources of the items are identified in Appendix B. The CTQ was created so that all of
the test items would be pertinent to the practice of psychology. The CTQ is intended
to tap into critical thinking in general, but also as it applies to practicing
psychologists. Therefore, the CTQ was created by adapting various, existing critical
thinking measure items to our specific population. Further, the CTQ requires less
time to complete than existing critical thinking measures.
Because the construct of “critical thinking” is a composite of a number of
specific skills and abilities, this assessment was developed to measure five specific
sub-areas of critical thinking. These five areas were derived from the Watson-Glaser
Critical Thinking Appraisal and the following descriptions are from the WGCTA
Manual. The critical thinking skills categories are used for the development of a
composite to test the construct of critical thinking.
The first area is inference, which is defined as “discriminating among degrees
of truth or falsity of inferences drawn from given data.” The second area is
recognition of assumptions, which is defined as “recognizing unstated assumptions or
presuppositions in given statements or assertions.” The third area is deduction, which
is defined as “determining whether certain conclusions necessarily follow from
information in given statements or premises.” The fourth area is interpretation, which
is defined as “weighing evidence and deciding if generalizations or conclusions based
on the given data are warranted.” The last area is evaluation of argument and is
defined as “distinguishing between arguments that are strong and relevant and those
that are weak or irrelevant to a particular question at issue” (Watson & Glaser, 1994,
pp. 9-10). The CTQ is made up of items from the WGCTA, the CCTT, and
Stanovich (2001) to provide a broad range of questions adaptable to psychologyrelated areas. The CTQ is a 28-item multiple-choice format measure. The participant
is provided with a range of two to six possible answers depending on the question.
Each item has only one correct answer. See Appendix B for the CTQ and Appendix
C for an index of item-by-item sources.
Treatment Approaches and Techniques Questionnaire (TATQ). Various
scales exist that assess clinicians’ theoretical orientation that tap into epistemic
variables (e.g., Theoretical Orientation Survey; TOS, Coan, 1979). This study
focused less on epistemology of practice in favor of topography of practice. In other
words, the goal was to know what clinicians’ actually do rather than what they think
they are doing.
The Treatment Approaches and Techniques Questionnaire (TATQ) was also
created for the purposes of this study (Appendix D). The measure consists of a list of
36 treatment approaches/techniques. The approaches/techniques are each associated
with one of six theoretical orientations with respect to psychotherapy. There are six
approaches/techniques from each of the following theoretical orientations:
systems/family systems, cognitive-behavioral, psychoanalytic/psychodynamic,
power/energy, existential/humanistic/phenomenological, and radical
behavioral/applied behavior analysis. The participant rates each item on a Likert
scale indicating their current or potential use of the approaches/techniques (0-never
use/would not use, 1-sometimes use/would possibly use, 2-frequently use/would
probably use, and 3-almost always use/would definitely use). The item order was
randomly assigned. See Appendix D for TATQ and Appendix E for match of items
and theoretical orientation.
2.4 Principal Hypotheses
1) Higher composite scores on a measure of Power/Energy Therapy
utilization will be related to significantly lower scores on the Critical
Thinking Questionnaire.
2) Higher composite scores on a measure of Cognitive-Behavioral Therapy
utilization will be related to significantly higher scores on the Critical
Thinking Questionnaire.
As noted above, 501 data packets were mailed to the following APA
divisions: 21 Fellows and 146 Members of Division 12 Clinical Psychology, 17
Fellows and 150 Members of Division 29 Psychotherapy, and 3 Fellows and 164
Members of Division 42-Psychologists in Independent Practice. 80 packets were
also mailed to members of the Association for Comprehensive Energy Psychology
(ACEP). Sixty-eight packets were returned as undeliverable. Six packets were
returned not completed due to either the recipient not being interested in participating
or notification that the recipient was deceased. Of the remaining 513 packets, 79
were returned: 63 from APA division sample and 16 from ACEP sample. This is an
approximately 15% response rate and is lower than anticipated.
An a priori power analysis was conducted to determine an appropriate sample
size for the multiple regression analysis testing the principal study hypotheses. Given
an α level of .05, medium effect size of r = .30, and the convention for power of .80, a
total sample size of 53 was viewed as appropriate for the main analysis. Post hoc
power analyses were conducted for the main statistical analysis. Using the
conventions of .05 for alpha level and a medium effect size of .30, the total sample
size of 79 provided power of .96 for the multiple regression analysis. This clearly
exceeds the convention for power of .80. Therefore, there was sufficient power for the
main analysis.

Demographic data are presented in Table 1. The third column of Table 1.
shows results from a 2000 survey of the APA membership (APA, 2000). It should be
noted that the APA survey included all members of the association and therefore was
comprised of psychologists outside of the practice domain (e.g., experimental
psychologists) as well. Overall, the present sample is quite comparable to the larger
membership of APA with respect to age, gender, ethnicity, and degree. Compared to
the APA data, the current sample included a slightly higher percentage of male
psychologists. The mean age of the APA sample was 52.2 years with a standard
deviation of 12.4 years (APA, 2000). The modal age range for the current sample
was 50-59 years. Due to limitations imposed by the Drexel University IRB,
participants of the current study were not asked to report their actual age. Thus, it is
difficult to compare the current sample to the APA survey data. However, it appears
that the current sample may have been, on average, slightly older than the APA
membership. In addition, as would be expected from a sample of practitioners, a
somewhat higher percentage of the current sample participants endorsed a Psy.D.
rather than a Ph.D. as the highest degree obtained.
Personal Characteristics. As shown in Table 1, 48 (60.8%) of the respondents
were men, 29 (36.7%) were women, and 2 (2.5%) declined to answer this question.
The median age range of respondents was 50-59 years. 82% of respondents (n=65)
described themselves as white or Caucasian, 1 person described him/herself as
African-American, 1 person described him/herself as Native American, and 12
respondents (15%) declined to answer this question.

Professional Characteristics. Fifty-six (70.9%) of the respondents reported a
Ph.D. as their highest obtained degree, 10 (12.7%) reported a Psy.D. as highest
obtained degree, 5 (6.3%) reported an Ed.D. as highest obtained degree, 6 (7.6%)
reported an M.A., M.S., or MEd. as the highest obtained degree, and 2 (2.5%)
declined to answer. The range of years since graduation was from 2-53 years with a
mean of 23 years, and median and mode of 25 years. The range of years of
experience as a clinician or therapist was from 3-54 years with a mean of 26 years,
median of 25.5 years, and mode of 20 years. The range of average hours per week
spent providing therapy or counseling was from 0-50 hours with a mean of 23.5
hours, median of 22.5 hours and mode of 20 hours per week. 54 (68.4%) of the
respondents reported independent practice as their primary work setting, 15 (19%)
reported an agency as their primary work setting, 7 (8.9%) reported an academic
work setting as primary, and 3 (3.8%) respondents declined to answer.
Twenty-four respondents (30.4%) identified Professional (practitionerscholar) as the model of their graduate program, 25 (31.6%) identified ProfessionalScientist (practitioner-scientist) as the model of their graduate program, 26 (32.9%)
identified a Scientist-practitioner (Boulder model) graduate program, and 4 (5.1%)
respondents declined to answer. As expected, participants listed an extensive variety
of Certifications/additional training. A total of 29 participants (36.8%) did not
provide a response to this part of the demographic form. The most common
responses were completion of a Post-doc (n=7); ABPP (n=7); training in EMDR Level
I (n=6) or Level II (n=7); training in TFT Level I (n=3), Level II (n=1), or TFTdx
(n=2), and EFT (n=4).
Theoretical Orientation. Respondents were asked to rank order the list of
theoretical orientations. Table 2 shows the number and percentage of responses of
each rank by theoretical orientation. Cognitive-behavioral and Eclectic orientations
were the two most ranked number one with 23 each (29.1%). The
Psychoanalytic/dynamic orientation was a close second with 20 responses (25.3%). 8
respondents (10.1%) ranked the Existential/Humanistic/Phenomenological orientation
number one. 3 (3.8%) of respondents ranked the Systems/Family Systems orientation
number one. Both the Radical Behavioral/ABA and Power/Energy orientations were
each ranked number one by only 2 respondents (2.5%). Orientations not ranked were
scored as zeros. If a respondent did not rank or differentiate the theoretical
orientations, but did endorse one or more (e.g., checkmarks, multiple orientations
ranked as 1) the endorsed items were each scored as a 1.
3.2 Critical Thinking Questionnaire (CTQ)
Seventy-eight Critical Thinking Questionnaires (CTQ’s) were completed.
Total score was calculated by summing the number of correct answers. Thus, total
scores could range from zero to 28. Unanswered questions were scored as incorrect.
Table 3. shows frequency and overall percentage of correct responses for each of the
items on the CTQ.
CTQ Total Score. The 63 member APA sample had a mean CTQ total score
of 21.70 (SD=3.43) and the 15 ACEP member sample had a mean CTQ total score of
20.13 (SD=4.17). There was not a statistically significant difference between groups
when comparing CTQ total scores between sample membership, t (77) = 1.581,
p=.118. There was also not a statistically significant difference between groups when

comparing CTQ total scores by gender, t (75) = .358, p = .765.
A one-way analysis of variance (ANOVA) did not reveal any statistically
significant differences when comparing CTQ scores by highest obtained degree,
F(3,73)=1.678, p=.179. A second one-way ANOVA revealed a marginally
statistically significant difference when comparing CTQ scores by work setting,
F(3,73)=2.406, p=.097. Tukey HSD post-hoc comparisons showed the largest mean
difference to be 2.16 points between the Independent Practice (n=54; M=20.78) and
Agency (n=15; M=22.93) work settings, p=.104. Thus, respondents that endorsed an
agency as their main work setting tended to have higher CTQ total scores than those
reporting independent practice as their main work setting. There were no significant
effects for the small number of participants endorsing an academic work setting (n=7;
M=22.29). A third one-way ANOVA also revealed a marginally statistically
significant difference when comparing CTQ scores by model of graduate program,
F(3,72)=2.595, p=.082. Tukey HSD post-hoc comparisons showed a mean difference
of 2.29 points between the Professional school model (M=20.21) and Boulder model
(M=22.50) that was approaching statistical significance, p=.066. Thus, graduates of
Boulder model programs tended to have higher total scores on the CTQ when
compared to graduates of Professional school programs. A fourth one-way ANOVA
did not find any statistically significant differences when comparing CTQ scores by
first rank-ordered orientation, F(5,69)=.300, p=.911. In other words, when
participants were grouped based on the theoretical orientation they ranked as most
descriptive, there were no significant differences in critical thinking scores.
A simultaneous multiple regression was conducted using age, average number
of hours per week providing therapy or counseling, years of experience as a
therapist/clinician, and years since graduation from highest degree as the predictor
variables and CTQ total score as the dependent variable. The results indicate that the
regression was a poor fit (R2adj = .094) but the overall relationship was significant (F4,
2.955, p<. 026). With other variables held constant, number of years of
experience was the only statistically significant predictor (β=-.463, p<.047). Thus,
when partialling out the variance of age, years since graduation, and number of hours
per week treating clients, an increase in years of experience as a clinician was
associated with a decrease in total scores on the CTQ.
CTQ Subscales. Inference, Interpretation, Deduction, Recognition of
Assumptions, and Evaluation of Assumption subscale scores were calculated by
adding the number of correct responses from each category. Table 4. shows the
number of items, range, mean, standard deviation, and mean percentage of correct
responses for each of the CTQ subscales.
Five independent-samples t-tests were conducted to examine whether group
differences existed on any of the subscales when comparing the APA sample to the
ACEP sample. T-tests were conducted using sample membership as the independent
variable (APA vs. ACEP) and each of the five CTQ subscales (total number of
correct items from each subscale) as the dependent variables. Two t-tests showed
significant effects by group. On the Interpretation and Deduction subscales, the APA
sample had significantly higher scores on both, t (76)=2.410, p<.018 and t
(76)=2.037, p<.045, respectively. On the Interpretation subscale, the means for APA

(M= 6.05) and ACEP (M=5.19) provided a mean difference effect size of .86. On the
Deduction subscale, the means for APA (M= 3.68) and ACEP (M=3.25) provided a
mean difference effect size of .43. Thus, while there were no mean differences on
CTQ total score by group membership, on the Interpretation and Deduction subscales
of the CTQ, APA members had significantly higher scores than ACEP members.
3.3 Treatment Approaches and Techniques Questionnaire (TATQ)
Seventy-eight TATQ’s were completed. Items that were left blank were
scored as a zero. Table 5. shows frequency of responses for each item on the TATQ.
Data Summarization. A principal components factor analysis with Varimax
rotation was conducted to examine the factor structure of the TATQ. Three
components were extracted and factor loadings of .6 or greater were considered
significant (Hair, Anderson, Tatham, & Black, 1995). The first factor is primarily
comprised of Cognitive-Behavioral, Radical Behavioral/ABA, and Systems/Family
Systems techniques. The second factor features five of the six
Psychoanalytic/Dynamic techniques (the free association item had a factor loading of
.589 and was thus excluded) and non-directive support and promotion of selfactualization, which were a priori considered techniques from the E/H/P orientation.
The third factor was made up of the six P/E techniques. In addition to free
association, four other techniques had nonsignificant loadings: mirroring,
unconditional positive regard, logotherapy, and re-authoring (see Table 6. for item
Composite Scores. Composite TATQ scores were created by adding the
participants’ responses from each of the theoretical orientation categories. Therefore,

Note: * indicates significant loading (i.e., Eigenvalue greater than .60)
each participant had a score between 0 and 18 for each of the theoretical orientations.
A score of zero would indicate that they answered 0 or Never use/Would not use for
all six of the therapeutic techniques from that theoretical orientation category. A
score of 18 would indicate that they endorsed a 3 or Almost always use/Would
definitely use for all six of the therapeutic techniques from that theoretical orientation
category. Means of composite scores can be used as an indicator of the popularity of
techniques from each of the theoretical orientations. When comparing mean
composite scores by sample type, there was only one significant difference: P/E
score. The mean P/E score of the APA sample was 1.03 with a standard deviation of
2.80. The mean P/E score of the ACEP was 9.56 with a standard deviation of 5.48.
A t-test revealed that this difference was significant, t (77) = -8.741, p< .0001,
ES=.84. Thus, not surprisingly, members of an organization devoted to
“comprehensive energy psychology” had significantly higher scores on the P/E
composite than did APA members.
A one-way analysis of variance (ANOVA) did not reveal any statistically
significant differences when comparing P/E scores by participants’ endorsed model
program, F(2,72)=1.464, p=.238. A second one-way ANOVA did not reveal any
statistically significant differences when comparing P/E scores by highest obtained
degree, F(3,73)=.917, p=.437. Thus, there were no statistically significant differences
on the Power/Energy composite scores when grouping participants by their degree or
model graduate program.
3.4 Multiple Regression Analyses
Composites. A simultaneous multiple regression was completed using the six
composite TATQ scores from each of the theoretical orientations as the predictor
variables and CTQ total score as the dependent variable. The results indicate that the
regression was a poor fit (R2adj = .114) but the overall relationship was significant (F6,
2.665, p<. 022). Two of the regression weights were significant and therefore
contributed to the multiple regression model: P/E score (β= -.341, p<. 008) and C/B
score (β= .371, p< .021). Thus, increases in Power/Energy scores predicted
decreases in Critical Thinking scores and increases in Cognitive-Behavioral scores
predicted increases in Critical Thinking scores.
A simple correlation between P/E scores and C/B scores was significant (r= .323,
p< .004). A simple correlation between P/E scores and CTQ total was negative and
significant (r= -.240 p< .033). A simple correlation between C/B scores and CTQ
total was not significant (r= .170, p= .134). However, because C/B scores and P/E
scores are significantly correlated, a partial correlation was done with C/B scores and
CTQ total partialling out the variance of P/E scores. This correlation was positive
and significant (r= .2694, p< .017). Further, a partial correlation between P/E scores
and CTQ total partialling out the variance of C/B scores was negative and significant
(r= -.3164 p< .005).
The relation between age and years since graduation and several of the
composite scores was examined using simple correlation analyses. Cognitivebehavioral composite scores were significantly negatively correlated with age (r=.312, p<.005) and years since graduation (r=-.285, p<.011). Dynamic scores were
significantly positively correlated with age (r=.260, p<.020) and years since
graduation (r=.245, p<.029). Power/Energy scores were negatively correlated with
age, although it was not statistically significant (r=.129, p<.257). However, P/E
scores were significantly negatively correlated with years since graduation (r=-.286,
p<.011). Also, further examination of the most frequently endorsed P/E technique,
bilateral stimulation, revealed a significant negative correlation with age (r=-.222,
p<.049) and years since graduation (r=-.331, p<.003). Therefore, an increase in age
and number of years since graduation coincided with an increase in Dynamic scores.
An increase in age and years since graduation coincided with a decrease in C/B and
P/E scores and rating of bilateral stimulation item on the TATQ.
Factors. A simultaneous multiple regression was conducted using the three
factors derived from the factor analysis as the predictor variables and the CTQ total
score as the dependent variable. The results indicate that the regression was a poor fit
(R2adj = .076) and the overall relationship was not significant (F6, 72= 2.058, p=. 113).
Therefore, several of the TATQ composite scores (P/E and C/B) were better
predictors of CTQ total score than were the components derived from the factor
The 15% response rate was lower than anticipated. One explanation is that
the questionnaires were time consuming and challenging; particularly the CTQ, and
most recipients chose not to or were unable to complete them. Despite the low
response rate, the sample size was deemed adequate to complete the proposed data
analyses. Based on comparing the sample demographic characteristics with the APA
membership survey data, the sample is judged to be appropriately representative of
practicing psychologists. Further, because of the low response rate, the results must
be interpreted with caution.
This study represents the first attempt to examine the role of critical thinking
in practitioners’ choice of therapeutic techniques. It is also one of the first studies to
go beyond the limited label of theoretical orientation and measure actual use of
therapy techniques. Because of the popularity of a number of varied techniques, we
can no longer infer from one’s stated theoretical orientation what is occurring behind
the office door, and this study bears that out.
With the partial exception of psychoanalytically and dynamically oriented
psychologists, most practitioners reported that they do or would utilize a number of
therapeutic techniques outside of their predominant orientation. Therefore, it can be
concluded that with the exception of a segment of analytically and dynamically
oriented practitioners, most psychologists appear to be eclectic in terms of their use of
techniques. It is unclear from the present data whether these practitioners are most
appropriately conceptualized as technically eclectic or unsystematically
eclectic/theoretical integrationist. It is likely that unsystematically eclectic would be
the most fitting description because the range of techniques utilized would be difficult
to reconcile under a single theoretical rubric, whether it be the theoretical orientations
described in this study or the category of empirically supported treatments. Future
research is needed to assess the role of empirical support for an intervention in
psychologists’ decision-making process.
4.1 Hypotheses
As hypothesized, participants who reported using a number of techniques
from Power and Energy therapies scored significantly lower on the measure of critical
thinking skills. Also as hypothesized, individuals who reported using a number of
Cognitive-Behavioral techniques scored significantly higher on the measure of
critical thinking skills. Thus, ability to think critically about therapeutic techniques
may impact psychologists’ choices. Relatively strong critical thinking skills likely
enable individuals to better evaluate information. For example, participants who
responded to the survey from the Association for Comprehensive Energy Psychology
reported significantly higher utilization of P/E therapies compared to the APA
members. When compared to the APA sample, ACEP members had significantly
lower scores on the Interpretation and Deduction subscales of the CTQ. If we revisit
the definitions for the constructs of interpretation, “weighing evidence and deciding
if generalizations or conclusions based on the given data are warranted” and
deduction, “determining whether certain conclusions necessarily flow from
information in given statements or premises,” it becomes clear how strengths or
deficits in these areas could impact use of novel treatments. Individuals skilled in the
areas of interpretation and deduction may determine that proposed evidence for the
efficacy of a novel treatment is not compelling.
It is unclear what accounts for the negative correlation between years of
experience and CTQ total. It is possible that this is an artifact of the relation between
age and the dynamic orientation. In other words, it is possible that individuals trained
in dynamic and analytic models experienced less emphasis on critical thinking skills
as compared to more recently trained individuals who are more likely to be trained in
the cognitive-behavioral model.
It should be noted that several of the cognitive behavioral techniques appeared
to be popular across participants. For example, only three respondents reported that
they never use or would not use cognitive restructuring. Inversely, most of the
Power/Energy techniques were not popular across all participants. For example,
approximately 81% of participants reported that they do not or would not use the
technique tapping of acupressure/acupuncture points. However, eight of the 63 APA
members and eight of the 16 ACEP members reported training in EMDR. Further,
roughly 30% of all participants responded that they use or would use bilateral
stimulation (e.g., eye movements). There was a significant negative correlation
between age and rating of bilateral stimulation as well as number of years since
graduation and rating of bilateral stimulation. Hence, the older and/or longer out of
graduate school the participant is, the less likely they would be to use techniques such
as EMDR. Future research should focus on the popularity of the Power/Energy
therapies with psychologists who have more recently completed their training. The
present sample appears to be a reasonably representative cross-section of
psychologists. Because the data indicate that younger and newer graduates are more
likely to be utilizing these techniques, the results of the current study may not be a
completely accurate assessment of the rise in use of these techniques. In other words,
these data may belie the actual upsurge in use.
4.2 Popularity of Therapies
Although they tend to be older and longer out of graduate school, practitioners
of psychoanalytic and psychodynamic therapies continue to comprise a significant
portion of practicing psychologists. Approximately 25% of the respondents ranked
the psychoanalytic/dynamic orientation as being most descriptive of themselves.
Further, factor analysis of the TATQ revealed that one of three factors was clearly
comprised of techniques from this orientation as well as non-directive support and
promotion of self-actualization. The latter two techniques were a priori
conceptualized as being from the Existential/Humanistic/Phenomenological
orientation. However, neither is incongruent with analytic or dynamic theory and
non-directive support is indeed a major component of its application. Additionally, it
appears that relative to the other theoretical orientations, psychologists that are
analytically/dynamically oriented often use techniques and approaches from their
orientation and are less likely to also use techniques and approaches from other
orientations. In other words, they are less technically eclectic.
Cognitive-Behavioral and Eclectic theoretical orientations were the two most
commonly reported as most descriptive, accounting for approximately 58% of the
number one rankings. It is also interesting that 71% of respondents ranked the
cognitive-behavioral orientation as first, second, or third. In other words, almost
three quarters of all psychologists considered themselves to be at least somewhat
Cognitive-Behavioral in orientation. Only fourteen did not rank it at all. Also, a vast
majority of participants reported that they use or would use most of the listed
Cognitive-Behavioral techniques including cognitive restructuring and social skills
training. This is regardless of described orientation.
These data suggest that identification with analytic and dynamic therapies is
waning and being supplanted by cognitive-behavioral treatments. Although only two
of the respondents reported the Power/Energy orientation as most descriptive, the
techniques from this orientation comprised another of the three factors. It is likely
that so few respondents labeled Power/Energy as their primary orientation because 1)
many do not practice these techniques, 2) those who do use these techniques view
them as falling under or congruent with other global theoretical orientations. In other
words, many practitioners who use Power/Energy techniques probably consider
themselves to be Cognitive-Behavioral or Eclectic in orientation. Among users of
Power/Energy therapies, EMDR and TFT appear to be the most popular.
Approximately 16% of all respondents reported certification in EMDR and 8% of all
respondents reported certification in TFT. However, this is probably an
underestimate of the use of these therapies considering approximately 38% of
respondents did not provide an answer for this non-compulsory question. Clearly, the
Power/Energy therapies have impacted professional psychology. Although the results
of this study do not indicate that Power/Energy therapies enjoy widespread use
among practicing psychologists, because of the relationship to age, they do suggest
that the impact may be growing. Further, the rise in popularity of Power/Energy
therapies may also be occurring largely outside of the domain of professional
psychology. Many users of Power/Energy therapies may come from social work and
other non-psychology fields.
The empirically supported treatment movement continues to be a contentious
issue. Further, the use of a variety of traditional techniques and therapies with little
or no empirical support (e.g., psychoanalytic therapy) continues, but may be waning.
The results of the present study are encouraging in that they do point to an increase in
use of empirically supported techniques and therapies relative to the findings of
previous research. Although it does not appear to be widespread, novel treatments
like the Power/Energy therapies are being used by a small percentage of practicing
psychologists. Additionally, the data seem to indicate that they are more popular with
younger and more recently trained psychologists. Thus, both a number of empirically
supported treatments (e.g., cognitive therapy) and novel unsupported treatments (e.g.,
TFT) appear to be gaining popularity while traditional psychotherapies (e.g.,
psychoanalytic psychotherapy) are being practiced less.
The data from the present study indicate a relationship between critical
thinking skills and therapeutic orientation. More specifically, cognitive-behavioral
therapists appear to have significantly stronger ability to think critically, while
therapists that employ a number of power/energy therapies appear to have a
significantly weaker ability to think critically. There are a number of possible
explanations for this phenomenon. One explanation is that practitioners with stronger
critical thinking skills are drawn to EST’s and practitioners with weaker critical
thinking skills are drawn to novel treatments, especially ones heavily marketed
directly to clinicians. However, this does not adequately explain the phenomenon,
especially when one considers the positive correlation between the cognitivebehavioral and power/energy composite scores. There were also not significant
differences on the power/energy composite scores when comparing participants by
type of degree and model of their graduate programs. However, further examination
is needed to evaluate the relationship between graduate training, critical, thinking
skills, and practical orientation.
Another more parsimonious explanation is that critical thinking skills act as a
set of filters for information. The stronger the critical thinking skills the more
effective the filters and the weaker the critical thinking skills the more porous the
filters. Thus, the practitioner with robust filters is a skeptic and only incorporates
techniques and approaches into his or her armamentarium after careful and critical
examination of available data. The practitioner who filters out less is more prone to
accept techniques and approaches prima facie with little or no critical examination.
These latter practitioners are more vulnerable to the extensive and often savvy
marketing frequently exhibited by promoters of novel treatments.
In the recently published book Science and Pseudoscience in Clinical
Psychology, editors Scott Lilienfeld, Steven Jay Lynn, and Jeffrey Lohr (2002)
conclude the text with a “prescription” for psychology training that starts with an
increased focus on critical thinking skills. The findings of this study lend further
support to that assertion. A literature search on the topic of critical thinking in
healthcare professions will yield literally thousands of citations from medicine and
nursing and almost none from professional psychology. A concerted effort to
intensify critical thinking skills training in the education of professional psychologists
may help to reduce the popularity of unsupported and dubious treatments.
Additionally, redoubling efforts to improve psychologists’ critical thinking skills may
help to encourage the use of empirically supported treatments.
4.3 Study Limitations and Recommendations for Future Research
As with all mail-survey based research, a low response rate presents a
limitation in the interpretation of the results. This is especially true in assessing the
popularity of various treatment approaches. Another potential limitation of the study
is the failure to differentiate actual use of various techniques from likelihood of use.
In other words, by asking participants whether they do or would use the listed
techniques, we are unable to determine actual use of the techniques. The TATQ will
be improved by asking respondents to rate both actual use and likelihood of use of the
listed techniques and approaches.
Future research is needed to assess factors that contribute to practitioners’
choice in therapeutic technique. For example, what percentage of practitioners use
cognitive restructuring because of the vast outcome literature supporting its
effectiveness with a variety of problems versus other factors (e.g., heavy emphasis in
graduate school, intuitive appeal, etc).
Future research is also needed to assess the popularity of Power/Energy
therapies in a broader range of mental health professionals. For example, it is likely
that many of these treatments are popular with social workers and other master’s level
clinicians not included in this study.

Instructions are provided for some of the exercises. Please make sure that all answers
are clearly marked. Thanks again for your participation!
Exercise 1
Imagine that disorder X occurs in one in every 1,000 people. Imagine also
there is a test to diagnose the disorder that always gives a positive result
when a person has the disorder. Finally, imagine that the test has a false
positive rate of 5 percent. This means that the test wrongly indicates that
the disorder is present in 5 percent of the cases where the person does
not have the disorder. Imagine that we choose a person randomly,
administer the test, and that it yields a positive result (indicates that the
person has the disorder). What is the probability that the individual actually
has the disorder, assuming that we know nothing else about the
individual's psychological or medical history?
A) < 10%
B) 10-30% C) 30-50%
D) 50-70%
E) 70-90%
F) >90%
Exercise 2
The next exercises consist of brief paragraphs followed by several conclusions. For
these questions please assume that everything in the paragraph is true. The problem is
to judge whether or not each of the proposed conclusions logically follows beyond a
reasonable doubt from the information given. Please mark either follows or does not
follow after the conclusion.

Exercise 5
Below are several questions followed by several arguments. For the purpose of this
study, please regard each argument as true. The problem then is to decide whether it
is a strong (it is important and directly related to the question) or weak (not directly
related to the question or related only to trivial aspects) argument. Remember that
each argument is to be regarded as true.
Question: Should the United States Department of Health and Human
Services keep the public informed of its anticipated scientific research
